The result is the highest level of insight into nonlinear device behavior, making the NVNA capability especially useful for scientists researching new RF technologies and engineers involved in designing today's high-performance active devices.
Under low levels of random excitation, the contribution from the nonlinear terms is negligible, the linear stiffness and linear damping are dominant, harvesters operate in the linear regime, and the response of a nonlinear device is just similar to a linear EMEH.
Devices such as cell phones or microwave ovens would not affect the nonlinear device, Karami said.
While the input signal may be a single tone, the output signal of a nonlinear device could contain distortion in the form of harmonics or other spurs.
However, unlike linear S-parameters, nonlinear large-signal S-parameters depend upon the signal magnitude and must account for the harmonic content of the input and output signals since energy can be transferred to other frequencies in a nonlinear device.
Nonlinearity means that what goes in does not necessarily come out in the same manner; put another way, not all light signals passing through a nonlinear device are treated equally.
The author covers fundamental MESFET, MOSFET, and PIN nonlinear device modeling, as well as transient and harmonic behavior in microwave semiconductors, nonideal device behavior in control circuits, switch and switched circuit applications, control and attenuator applications, and many other related subjects.

Moreover, it will also be shown that, despite the variability in nonlinear device models and the levels of detail being dealt with, a large range of device technologies share a very similar set of IMD characteristics.
These very fast photoreceivers can be used as transfer standards to establish absolute electrical phase, a critical quantity required for nonlinear device characterization at microwave frequencies, and to push calibrated temporal measurements to microwave frequencies, creating a new microwave-measurement paradigm.
It is widely used in the optimization of passive components and microwave nonlinear device modeling [13-18].
